ENTERING COMMANDS
This section describes how to enter CLI commands.
KEYWORDS AND
ARGUMENTS
A CLI command is a series of keywords and arguments. Keywords identify
a command, and arguments specify configuration parameters. For
example, in the command “show interfaces ethernet,” show and
interfaces are keywords, and ethernet is an argument that specifies the
interface type.
You can enter commands as follows:
◆ To enter a simple command, enter the command keyword.
◆ To enter commands that require parameters, enter the required
parameters after the command keyword. For example, to set a
password for the administrator, enter:
Enterprise AP(config)#username smith
MINIMUM
ABBREVIATION
The CLI will accept a minimum number of characters that uniquely identify
a command. For example, the command “configure” can be entered as
con. If an entry is ambiguous, the system will prompt for further input.
COMMAND
COMPLETION
If you terminate input with a Tab key, the CLI will print the remaining
characters of a partial keyword up to the point of ambiguity. In the
“configure” example, typing con followed by a tab will result in printing the
command up to “configure.”
GETTING HELP ON
COMMANDS
You can display a brief description of the help system by entering the help
command. You can also display command syntax by following a command
with the “?” character to list keywords or parameters.
SHOWING COMMANDS If you enter a “?” at the command prompt, the system will display the first
level of keywords for the current configuration mode (Exec, Global
Configuration, or Interface). You can also display a list of valid keywords
for a specific command. For example, the command “show ?” displays a
list of possible show commands:
AP: show ?
APmanagement Show management AP information.
authentication Show Authentication parameters.
bridge Show bridge.
config Show current configuration.
event-log Show event log on console.
dual-image Show dual images version.
